Abstract
The utility model provides an automatic control device for stopping a rolling mill urgently, which is mainly composed of an intertripping loop using a connection point K1 on a manual stop button to control a relay K3 and an electric drive and control loop of the rolling mill controlled by a relay connection point K3 in the intertripping loop. A digital quantity output connection point K4 of a PLC is used for controlling a relay connection point K2 which is connected in series in the intertripping loop. The utility model solves the problems that band steel is piled up and stacked because manual operation is out of time, surrounding auxiliary equipment of the rolling mill is run down, etc., realizes automatic and quick stopping when emergency is generated, and simultaneously has the advantages of simple structure, quickness and reliability.
Description
Affiliated field
The utility model relates to the electric wiring automaton, the automaton that especially a kind of milling train stops in emergency.
Background technology
In the belt steel rolling system, be subjected to bigger infringement when the burst accident for fear of milling equipment, generally be equipped with a manual emergency stop push button device, this device is mainly formed by the intertripping loop of coming control relay K3 by a contact K1 on the manual stop button and by the part of the milling train Electrified Transmission that relay tip K3 controlled in the manual control loop.When emergency episode takes place when, production operator can take hand push button rapidly with hand, milling train Electrified Transmission control loop disconnects, milling train just can stop operating, the band steel also stops to be fed forward, and after avoiding quick band steel forward to be stuck in a certain position of milling train, band steel rear portion still fast forward, and cause band steel bulk, stacked, the milling train auxiliary device around breaking.And owing to people's brain, the reaction needed regular hour of hand, transporting velocity with steel can reach several metre per second (m/s)s even tens metre per second (m/s)s again, emergency episode takes place after, if slow slightly several seconds of the reaction of production operator, to have in the milling train tens meters long the band steel bulk together, equipment is caused great infringement.As seen, have only manual emergency stop (apparatus) can not farthest protect milling equipment.
Summary of the invention
The automaton that provides a kind of milling train to stop in emergency is provided the purpose of this utility model, so that the purpose that realizes when emergency episode takes place automatically, stops fast.
The purpose of this utility model is to realize like this, the automaton that this milling train stops in emergency is mainly by coming the intertripping loop of control relay K3 by a contact K1 on the manual stop button and being made up of the milling train Electrified Transmission control loop that the contact of the relay K in the intertripping loop 3 is controlled, by relay K 2 of output contact K4 control of the judgement accident condition of PLC, and this relay tip K2 is connected in series in the intertripping loop goes.
The utility model is owing to sealed in a relay tip K2 who is subjected to the output point control of PLC in former manual anxious fixed-position stop control apparatus, realized purpose automatic when emergency episode takes place, that stop fast, solved because of manual operation is untimely and caused band steel bulk, stacked, broken problems such as milling train auxiliary device on every side.Has advantage simple in structure, rapid, reliable simultaneously.
Description of drawings
Fig. 1 is an electrical schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, the automaton that milling train of the present utility model stops in emergency is mainly by coming the intertripping loop of control relay K3 by a contact K1 on the manual stop button and being made up of the milling train Electrified Transmission control loop that the contact of the relay K in the intertripping loop 3 is controlled, by relay K 2 of the digital quantity output contact K4 of PLC control, and the contact of this relay K 2 is connected in series in the intertripping loop goes.
As shown in Figure 1, a contact K1 on the manual stop button in the utility model is a normally closed contact, and the relay tip K3 that is connected in the milling train Electrified Transmission control loop is a normal opened contact.And automatic stopping relay tip K2 state is the digital quantity output contact K4 state of Chang Kai or the normally closed PLC of depending primarily on, digital quantity output contact K4 as PLC is a normally closed contact, and being subjected to the contact K2 that is connected in series on the relay K 2 in the intertripping loop of this contact K4 control is normal opened contact; Digital quantity output contact K4 as PLC is a normal opened contact, and being subjected to the contact K2 that is connected in series on the relay K 2 in the intertripping loop of this contact K4 control is normally closed contact.
The utility model is in use according to the judgement of making in the PLC program to accident condition, digital quantity signal control relay K2 of PLC output contact K4 output when the steel-fastening accident takes place, the contact K2 action of this relay, the intertripping loop disconnects, relay K 3 dead electricity, milling train Electrified Transmission control loop disconnects, thereby makes milling train automatic stopping in the shortest time.The utility model is equally applicable to solve urgent self-stopping problem in other metallurgical electrical equipment.
Claims (3)
